Title: Process for enhanced delayed in situ gelation of chromium polyacrylamide gels
Inventor: TACKETT JAMES E JR
IPC: C09K8/512
Filed: 1991-07-02
Granted: 1995-08-01
Abstract: The present invention is a process for selectively plugging high permeability zones of a subterranean hydrocarbon-bearing formation by enhancing the delay associated with the in situ formation of a polymer gel. The process comprises predetermining a gelation delay time based on a formation's temperature, permeability and porosity, the distance from the well bore a region to be plugged is located, and a volumetric rate of gelation fluid injection. A gelation solution is then prepared comprising polyacryla-mide a polyvalent metal carboxylate crosslinking agent, a gelation delaying agent and a buffer with a pKa of about 3.5 to about 6.8. Gelation delays are achieved by selecting the polyacrylamide concentration, delaying agent concentration and type, and buf-fer concentration and type, for given formation conditions. Delay times can range from several hours to several weeks at forma-tion temperature near 176 °F (80 °C) and from several hours to about one day at formation temperature above about 219 °F (104 °C). The prepared solution is then injected into the formation via a well bore and allowed to gel. The gel selectively plugs high permeability zones within a subterranean hydrocarbon-bearing formation, at temperatures and distances from the well for-merly unobtainable, resulting in improved vertical or areal conformance of injected fluids and improved oil production.

Title: Dynamically biased amplifier
Inventor: MARTIN WILLIAM J
IPC: H04W28/04
Filed: 1991-11-15
Granted: 1995-08-22
Abstract: An amplifier (102) which can be dynamically biased is disclosed.  A controller (118) determines when to change the bias to the amplifier (102), in order to achieve low frequency splatter. This is accomplished by changing the bias level of amplifier (102) between a substantially linear (class A) mode of operation, and a substantially nonlinear (class B) mode of operation. During the critical periods when the amplifier (102) is being turned into and out of operation, the amplifier (102) is placed in a substantially linear mode of operation, thereby reducing the output harmonics which develop. In another aspect of the invention a radio (300) which employs a dynamically biased amplifier (102) is disclosed. ~

Filed: 1993-08-16
Granted: 1997-02-18
Abstract: A waterproofed, insulated conductor or cable and a method of fabricating the same using a new slushing compound is described.  The waterproofed insulated conductor or cable includes a core with at least one conductor element, a polymeric insulation jacket, at least one textile covering over the polymeric jacket, and at least one waterproof coating on top of said at least one textile covering, the waterproof coating comprising a blend of from 15 to 40, preferably 20, weight percent of pine tar oil, the remainder being essentially natural (Trinidad) asphalt.

Pine tar oil-based blends demonstrate mechanical physical and handling characteristics comparable to cables waterproofed with prior-art coal tar oil-based blends.  Furthermore, the new blends use lesser quantities of pine tar oil than the quantity of coal tar oil in the prior-art blends, leading to lower losses of oil prior to and during the application of hot blends.

Abstract: The temperature of a heat reservoir is varied according to a linear function which is AC modulated. At the same time, a temperature difference between two points located in a heat flow path from the heat reservoir to an unknown sample is measured. The temperature difference between two points located in a heat flow path from the heat reservoir to a reference sample is also measured. These two pairs of points are arranged symmetrically. The resulting DSC (differential scanning calorimeter) signals are demodulated, and each signal is divided into an AC component signal and a low-frequency component signal. Using these signals, the DSC signal is separated into a heat capacity component and a latent heat component.

Filed: 1994-12-06
Granted: 1998-06-09
Abstract: Ultrasonic wave is emitted into an examined body. A first electric echo signal is generated in response to an echo of the ultrasonic wave. A controllable filter responsive to a control signal serves to extract components of the first electric echo signal which are in a desired frequency band, so that the first electric echo signal is converted into a second electric echo signal. A logarithmic detection device serves to subject the second electric echo signal to logarithmic compression and detection. A signal generator is operative for outputting plural calibration signals having different frequencies and different amplitudes. An input selection device is operative for connecting the signal generator with an input terminal of the filter during a calibration mode of operation. A control device is operative for calculating a corrective, value from an output signal of the logarithmic detection device during the calibration mode of operation, and correcting a logarithmic conversion characteristic and an offset of the logarithmic detection device and the control signal to the filter in response to the calculated corrective value during reception of echoes of the ultrasonic wave.
